What it is

Ferrous gluconate is an iron salt of gluconic acid. Gluconic acid is produced by the fermentation of glucose, typically from corn or wheat. Ferrous gluconate is then synthesized by reacting gluconic acid with an iron source.

Why it's used

Manufacturers add ferrous gluconate to help stabilize the color of foods, particularly in products like olives and pickles. It can prevent browning and maintain a more appealing appearance. It is often found in pickled vegetables and savory snacks.

Health notes

Ferrous gluconate is generally recognized as safe (GRAS) by the FDA for use as a nutrient supplement and color stabilizer. It is a source of iron, an essential mineral. International bodies like JECFA have evaluated it. At typical intake levels found in food, it is not associated with adverse health effects.

Allergen info

Ferrous gluconate is not derived from any of the 9 FDA major allergens. It does not contain gluten.
